Objectives
OPTI6 evaluates the integration of satellite-based optical communications within the context of future 6G-based integrated terrestrial-space networks. The study begins by analysing the use cases and technical scenarios for systems relying on optical links to carry 6G traffic (see Figure 1). Based on this analysis, potential architectures will be defined to establish the 6G protocol layers required for satellite network integration.
Particular emphasis will be placed on defining optical interfaces, aligned with standards such as ESTOL, to ensure network interoperability and the development of integrated networks where the protocol operates seamlessly and transparently for users.
The proposed system will be analysed and simulated using software to identify the technological gaps that need to be addressed.
Benefits
OPTI6 paves the way for integrating the future 6G protocol into satellite optical networks. Furthermore, it will facilitate the integration of space and terrestrial networks, providing users with seamless, high-performance connectivity.
OPTI6 will pave the way for new technologies that integrate space-based optical systems with a cross-layer protocol independent of the connectivity medium.
Features
Strong emphasis on systems, architecture, and technological definition.
Challenges
The key challenge of OPTI6 Study is as in following:
• Contribution to the development of space-to-space and space-to-ground integrated optical networks.
• Contribution to the development of the 6G ecosystem, extending into the space and optical space domains.
• Aligning user service requirements with access infrastructures that are available everywhere and offer the best Quality of Service (QoS).
System Architecture
The system architecture will be defined during the study execution.
Plan
The project has a duration of one year and consists of a single phase. The project plan is as in the figure below.
Current Status
• The project kicked off in mid July 2026
• First review (SotA Critical Review) is scheduled for October 2026
